L-Carnitine & Acetyl-L-Carnitine

Proxeed® plus is a complete carnitine-based formula for male fertility that targets multiple sperm functions. Playing a key role in supporting normal sperm developmentǂ and included in Proxeed® plus are L-Carnitine (LC) (fumarate) and Acetyl-L-carnitine (ALC). 
  • Carnitines are among the most clinically supported ingredient compared to all other nutrients in the field of male fertilityǂ.
    • Some patients have lower levels of L-carnitine (LC) and Acetyl-L-Carnitine (ALC) in seminal plasma. In men, a balanced LC: ALC ratio can help:
      • Maintain seminal plasma levelsǂ
      • Maintain sperm healthǂ
      • Maintain sperm quality, an essential factor in a couple’s fertilityǂ
    • Acetyl-L-Carnitine serves as a circulating energy source for sperm and provides primary fuel for sperm motility 5-8
    • LC/ALC supports the following functions
      • sperm motility morphology, concentration and count 17-20
      • supports normal sperm development in the presence of free radicals 9,14-16, 27ǂ
      • sperm factors affected: count concentration and motilityǂ

Each packet of Proxeed® plus contains 1.7 grams of L-Carnitine fumarate (1.0g of L-Carnitine) and 0.5g of Acetyl-L-carnitine.

Selenium

Proxeed® plus is a complete carnitine-based formula for male fertility that targets multiple sperm functionsǂ.
  • Selenium is a powerful antioxidantǂ
  • Selenium aids in the integrity of the sperm flagella to support motility and rapid linear progression11ǂ

  Each packet of Proxeed® plus delivers 50 mcg of Selenium, 71% of the daily recommended value.

Zinc

Proxeed® plus is a prenatal male supplement combining a unique blend of ingredients to support male fertility and sperm healthǂ.
  • Zinc, blended into Proxeed® plus is important for
    • Semen production and contributes to fertility and reproduction12ǂ.

1 packet of Proxeed® plus delivers 10 mg, 67% of the daily value, of zinc.

Coenzyme Q10

Proxeed® plus is a complete carnitine-based formula including antioxidant and energy-promoting agent Coenzyme Q10, to support male fertility and sperm healthǂ.
  • Coenzyme Q10 is an antioxidant
    • Antioxidants are important support for free radical balance in male fertilityǂ.
  • Coenzyme Q10 is also a metabolic substrate and is concentrated in the mitochondria of the mid-piece of the sperm
    • Supporting cellular energy; maintains integrity of sperm flagellaǂ21,22
  • Sperm factors affected: Motilityǂ17,21,22.

Proxeed® plus contains 20 mg of Coenzyme Q10 in each packet.

Vitamin C

Proxeed® plus is a complete carnitine based formula combining a unique blend of ingredients, to support sperm health such as Vitamin C, an antioxidant present in the seminal plasmaǂ.
  • Vitamin C is a key antioxidant that supports sperm metabolic processes:
    • Antioxidants in seminal plasma supports motility23ǂ
    • Sperm factors affected
      • Countǂ
      • Concentrationǂ
      • Motilityǂ

Each packet of Proxeed® plus contains 90 mg of Vitamin C (as L-Ascorbic Acid) to deliver 150% of the daily value

Folic Acid

Proxeed® plus is a complete carnitine based formula for male fertility that targets multiple sperm functionsǂ.
  • Folic acid, most commonly found in leafy greens, is essential during cell maturation and contributes to the quality of seminal fluid 13,8ǂ.
  • Studies suggest that supplementation of folic acid, along with zinc, improves sperm healthǂ

Each packet of Proxeed® plus contains 200 mcg of folic acid (50% of the daily value).

Vitamin B12

Proxeed® plus supports normal sperm development, male fertility and reproductionǂ.
  • Vitamin B12 is involved in cell maturation and DNA synthesis.
  • Deficiencies in B12 have been associated with decreased sperm count and motilityǂ.

1 packet of Proxeed® plus contains 1.5 mcg of this essential nutrient providing 25% of the daily value.
